Common Questions

What does P055E mean and how does it affect my car?

The P055E code indicates a problem with the power steering pressure sensor circuit. This can lead to difficulty in steering, affecting handling and safety. If left unaddressed, it can result in greater wear on the steering system and potentially hazardous driving conditions.

What are the most common causes of P055E and how much does it cost to fix?

The most common causes include a faulty power steering pressure sensor, damaged wiring, or a malfunctioning power steering pump. Repair costs can range from $100 to $300, depending on the specific issue and required parts.

Can I drive my car with P055E or should I stop immediately?

While you might be able to drive short distances, it's not advisable to ignore the P055E code. The steering may become stiffer, making it harder to control the vehicle, which can be dangerous. It's best to have it diagnosed and repaired as soon as possible.

How can I diagnose P055E myself using GeekOBD APP?

Using the GeekOBD APP, you can scan for trouble codes, view freeze frame data for context, and monitor live data from the power steering sensor. This information helps identify whether the sensor itself is faulty or if wiring issues are present.

What vehicles are most commonly affected by P055E?

The P055E code is frequently seen in 2015-2020 Ford F-150, Chrysler 300, and Jeep Grand Cherokee models. Always check for any recalls or technical service bulletins related to the steering system.

How can I prevent P055E from happening again?

To prevent the P055E code from recurring, regularly inspect your power steering system for leaks, ensure proper fluid levels, and check wiring connections for wear or corrosion. Routine maintenance can help catch issues before they escalate.

What is P055E?

The P055E diagnostic trouble code (DTC) indicates a problem with the power steering pressure sensor circuit in your vehicle. This code is primarily seen in various Ford, Chrysler, and Jeep models, particularly those manufactured between 2015 and 2020. The power steering pressure sensor is crucial because it measures the amount of hydraulic pressure produced by the power steering pump. If the pressure is outside of the expected range, it can lead to steering difficulties and affect overall vehicle handling. When the vehicle's onboard computer detects that the signal from the sensor is too high or too low, it triggers the P055E code. Common symptoms may include a stiff steering wheel, a warning light on the dashboard, or even unusual noises when steering. It's essential to address this issue promptly as it can lead to more severe steering system failures if left unchecked. Ignoring the P055E code could result in increased repair costs in the long run, as the power steering system is vital for safe vehicle operation.

System: P - Powertrain (Engine, Transmission, Emissions)

Symptoms

Common symptoms when P055E is present:

  • The check engine light may illuminate, signaling an issue with the vehicle's power steering system.
  • Drivers might experience a stiff or unresponsive steering wheel, making it difficult to maneuver the vehicle, especially at low speeds.
  • Fuel economy could decrease significantly, with reports of a 10-15% drop due to increased effort required to steer.
  • Strange noises, such as whining or grinding, may be heard when turning the steering wheel, indicating potential power steering pump failure.
  • Fluid leaks around the power steering pump or hoses could also be observed, suggesting a more extensive issue within the power steering system.

Possible Causes

Most common causes of P055E (ordered by frequency):

  1. The most common cause of the P055E code is a faulty power steering pressure sensor, which accounts for approximately 60% of occurrences. Replacing the sensor usually resolves the issue.
  2. Another common cause is damaged wiring or connectors in the power steering system. Corrosion or breaks in the wiring can lead to incorrect readings and trigger the P055E code.
  3. A malfunctioning power steering pump can also result in incorrect pressure readings, leading to the P055E code. Regular maintenance and fluid checks can help prevent this.
  4. Less commonly, a software issue in the vehicle's ECU may cause erroneous readings from the pressure sensor. Updating the ECU software can sometimes resolve this.
  5. In rare cases, a complete power steering system failure could trigger the P055E code, necessitating more extensive repairs or replacements.
